Abstract: IMPROVEMENTS IN CONTROLLED FLUID DISPERSAL TECHNIQUES                ABSTRACT OF THE DISCLOSURE         A liquid spray is characterized by a liquid jet which is cyclically deflected at a high frequency such that it breaks up into a fan-shaped spray pattern in which the fluid distribution and droplet size can be controlled.  Jet deflection is accomplished with energy in the pressurized liquid itself.          In a preferred embodiment, the spray is produced by a fluidic oscillator, of the type having a flow-reversing interaction region terminated by an outlet throat from which outlet walls diverge, configured to establish a static operating pressure at the upstream end of the interaction region which is positive relative to the pressure in the outlet region.  When the power jet is directed along one outlet wall it merges with working fluid outflow from a control passage communicating from that outlet wall to the upstream end of the interaction, whereas the opposite control passage remains filled with operating fluid because of the positive interaction region pressure, with the result that neither working nor ambient fluid is ingested into the interaction region from the outlet region.  Oscillation is produced by the fact that the pressure in the control passage conducting outflow is less than the pressure in the other control passage, the differential pressure deflecting the jet and thereby reversing the pressure conditions in the control passages.  The configuration for achieving this operation is characterized by: an outlet throat sufficiently narrow to permit the egressing oscillating jet to continuously isolate the interaction and outlet regions; and a short interaction region.  The oscillator is capable of delivering liquid sprays having uniform spatial distribution and uniform droplet size and is also operable with air or fluidized solid working fluid.          Oscillator frequency depends upon size of the oscillator and the applied pressure.

Abstract: LUMBER INSPECTION AND OPTIMIZATION SYSTEM            ABSTRACT A lumber inspection and optimization system is disclosed combining the speed of electro-optic scanning for flaw detection with electronic data manipulation and computation for optimizing the utilization of the lumber in accordance with an order entry list specifying the dimensions, grade and priority of boards desired to cut from each piece of lumber inspected by the system.  The system receives input data from an order entry device and an electro-optical scanner.  The digital scan data from the electro-optical scanner is electronically processed to form a flaw data buffer containing the edge location of all the detected flaws enlarged to compensate for defective material usually surrounding each flaw. Optimization of the material is accomplished by electronically comparing the order entry data with the location of the flaws in the flaw buffer to generate cut line data indicative of where the board is to be cut.  The cut line data may be used to either actuate a saw to cut the lumber at the locations specified by the cut line data or actuate a marker to mark the lumber at the specified locations.  When the order entry data includes pieces having permitted defects, the disclosed system includes a defect classification input device permitting a human inspector to insert defect classification data into the flaw data buffer prior to optimization.  The preferred embodiment utilizes a mini computer programmed to process the flaw data, optimize the utilization of the board inspected and generate the cut line data.

Abstract: ABSTRACT OF THE DISCLOSURE            As the applicator is propelled about the surface to be treated, hollow spikes called tines or tongs are alternately thrust, vertically downwards below the surface and withdrawn vertically upwards.  A bulk supply of treating liquid is maintained separate from the applicator, so the applicator is more maneuverable and less bulky.  The supply is pressurized and supplied to the applicator via a high pressure hose line.  The drive for reciprocating the tongs also powers a flow-dividing valve, which supplies the treating liquid to each of the tongs in turn, so that each tong liquid injects only when that tong is under the ground surface.

Title: Electrochemical cell using a dithionite radical of an  alkaline metal as the charge-transfer agent

Abstract: ABSTRACT OF THE DISCLOSURE            An ambient temperature electric cell of primary and secondary nature, characterized by the use of a dithionite radical of an alkaline metal as the charge transfer agent, and including processes for manufacturing and for operating the same.  The dithionite is dissolved in an anhydrous electrolyte comprised of a suitable solvent, which may also contain a salt of the same alkaline metal and be saturated with sulfur dioxide. A sealed and evacuated cell (negative electrode, inert highly porous space, and positive current gathering electrode) is filled with the electrolyte and subjected to a charging current sufficient to plate the alkaline metal onto the negative electrode while further saturating the electrolyte with sulfur dioxide.  In the case of a secondary cell, the electrolyte is capable of redissolving the dithionite produced upon discharge, such procedure being enhanced by a system for forced circulation of the electrolyte.  In the case of a primary cell, redissolution is not necessary and the final cell potential and discharge characteristics can be enhanced by replacing the dithionite electrolyte with other anhydrous electrolyte solutions (e.g., sulfuryl chloride or thionyl chloride),  The cell is characterized by extremely low internal resistance, long shelf life, excellent performance over a wide temperature range, and negligible depletion of the active dithionite charge transfer agent. In a particular high energy battery system, an electrolyte containing dissolved dithionite is circulated between a battery chamber and an auxiliary chamber containing solid dithionite salt (e.g., lithium dithionite).  The electrolyte circulates from the auxiliary chamber through a solids separating means (centrifugal separator) to the battery chamber, where the electrolyte containing freshly dissolved dithionite is passed through a highly porous intermediate passage between an elongate active anode (e.g., copper) and an adjacent elongate current gathering cathode (e.g., finely divided carbon), in such fashion as to minimize internal resistance to current flow while substantially increasing the energy storage capacity of the battery cell.

Abstract: ABSTRACT OF THE DISCLOSURE    A support material for platinum, platinum alloys, or other noble metal catalyst, is made from carbon particles by heat treating the carbon until it is at least partially graphitized, depositing a metal on the ?eat treated carbon particles which will catalyze the oxidation of graphite in an oxidizing atmosphere, ant oxidizing the surfaces of the heat treated carbon particles at the sites of the catalyst crystals to pit or etch the surfaces at these sites.  When this material is used as a support for platinum it reduces the rate of platinum migration when the supported platinum catalyst is heated in the presence of a liquid, thereby reducing the loss of platinum surface area which often occurs under these conditions.
